How to change the color of points in a scatterplot using ggplot2 in R?

To color the points in a scatterplot using ggplot2, we can use colour argument inside geom_point with aes. The color can be passed in multiple ways, one such way is to name the particular color and the other way is to giving a range or using a variable. If range or a variable will be used then the color of the points will be in different shades.

Example

ggplot(df,aes(x,y))+geom_point(aes(colour=x))

Output
